Hair Colour Chart Wheel: How to Choose the Right Hair Color and Undertone

Choosing a new hair color is harder than pointing at a beautiful shade on a box or showing your stylist a photo from social media. Two people can use what appears to be the same blonde, brown, copper, or red formula and end up with noticeably different results. Your starting hair level, natural underlying pigment, previous color, porosity, skin undertone, and the tones added during coloring all influence the final shade. This is where a hair colour chart wheel becomes genuinely useful.

Professional colorists use color theory to understand which shades complement each other and, more importantly, which colors neutralize unwanted tones. Violet can counter yellow, blue can balance orange, and green can reduce red. Wella’s professional education material describes the color wheel as a fundamental tool for understanding color and confirms that opposite colors neutralize one another.

But the color wheel is only one part of choosing hair color. You also need to understand hair levels, exposed undertones, warm versus cool shades, and your desired result.

This guide breaks the entire process down in practical terms so you can choose a more flattering shade and understand what your stylist means when discussing levels, tones, brassiness, ash, violet, gold, copper, or neutral color.

What Is a Hair Colour Chart Wheel?

A hair colour chart wheel is a version of the traditional color wheel adapted to hair coloring. It shows the relationships between primary, secondary, and complementary colors so colorists can predict how pigments will interact.

The basic primary colors are:

When primary colors are combined, they create secondary colors:

Between these primary and secondary colors are numerous intermediate or tertiary shades.

For hair coloring, the most important concept is opposition. Colors positioned opposite each other on the wheel neutralize one another. Professional Wella education materials use exactly this principle when explaining correction of unwanted hair tones.

The three combinations you should remember are:

Unwanted Hair ToneNeutralizing Color
YellowViolet/Purple
OrangeBlue
RedGreen

This is why purple shampoo is marketed to blondes with yellow brassiness and blue-based products are often used on darker blondes or brunettes showing orange warmth. Wella’s current professional guidance confirms that violet balances yellow, blue counteracts orange, and green reduces red.

However, the wheel does not automatically tell you which permanent color to buy. It tells you how colors relate.

You still need to determine how light or dark your hair is and which underlying pigment is present before choosing the correct toner or dye.

Understanding Hair Color Levels Before Choosing a Shade

One of the biggest mistakes people make is focusing on color names such as “ash blonde,” “chocolate brown,” or “caramel” without considering level.

Hair color level refers to how light or dark the hair is.

Professional color systems commonly use numbered levels progressing from very dark to very light, although exact naming and numbering can vary slightly by manufacturer.

A simplified level guide looks like this:

Approximate LevelGeneral Description
1Black
2Very dark brown
3Dark brown
4Medium brown
5Light brown
6Dark blonde
7Medium blonde
8Light blonde
9Very light blonde
10Lightest/pale blonde

Think of level as depth and tone as color character.

For example, two people could both have level 7 hair, but one might have:

The depth is similar, but the visual result is very different.

Wella’s professional shade-numbering guidance similarly separates depth from major and minor tonal directions.

This becomes particularly important when correcting unwanted color.

If someone has level 7 hair showing orange, simply buying an extremely light violet toner because “purple cancels brass” may not produce the desired result. Orange requires blue, while violet is more directly suited to yellow.

Your chosen toner must also be appropriate for the hair’s existing level.

Color theory works only when level and tone are considered together.

What Is an Undertone in Hair Color?

The word “undertone” can refer to two different things in hair coloring, which causes a lot of confusion.

First, there is the underlying pigment inside the hair that becomes visible as hair is lightened.

Second, there is your skin undertone, which can influence whether warm, cool, or neutral hair colors are visually flattering.

Let’s deal with the hair itself first.

Dark natural hair contains underlying warm pigments. As hair is progressively lightened, those pigments become visible. Professional colorists often refer to this progression as the lightening curve.

A simplified version looks roughly like this:

Wella’s professional technical material illustrates this same principle, showing red, orange, yellow, and pale-yellow pigments appearing at different stages of lift.

This explains why someone with naturally dark brown hair cannot usually jump directly to a clean icy blonde merely by applying blonde dye.

The hair must first become light enough.

If it stops at an orange stage, violet toner alone cannot transform it into platinum because the underlying level is still too dark and too orange.

This is one of the most important things the hair colour chart wheel cannot fix by itself.

A toner modifies tone. It does not magically create missing lightness.

How the Hair Colour Chart Wheel Neutralizes Brassiness

“Brassy” is a broad word that people use for several unwanted warm colors.

That creates bad color corrections because yellow, orange, and red require different neutralizing pigments.

Yellow Hair → Violet

Yellow and violet sit opposite one another on the wheel.

Therefore, violet pigment can visually neutralize excessive yellow.

This is the principle behind purple shampoos and violet toners. Wella’s current professional guidance specifically recommends violet for unwanted yellow tones.

Purple products work best when the unwanted warmth is actually yellow.

They are especially relevant to:

Orange Hair → Blue

Orange sits opposite blue.

Therefore, blue is the corrective direction for genuinely orange hair.

This is more common when naturally darker hair is lifted but does not reach pale blonde. Wella’s guidance on orange hair confirms that blue pigment helps cool excessive orange tones.

Red Hair → Green

Red is opposite green.

A green or matte tonal direction can therefore help reduce excessive red.

This principle is useful when trying to move a red-heavy brunette toward a more neutral or cool brown.

But neutralization must be controlled.

Too much corrective pigment can swing the result in the opposite direction. Excess blue on very yellow hair can contribute to a greenish appearance, for example.

Professional color correction is not simply “add the opposite color until the problem disappears.” Correct formulation depends on the amount of unwanted pigment, hair level, porosity, and intended final tone.

Warm, Cool, and Neutral Hair Colors Explained

Once you understand the corrective side of the color wheel, the next step is learning the difference between warm, cool, and neutral shades.

Warm Hair Colors

Warm shades contain visible red, orange, yellow, or golden influence.

Examples include:

Warm hair can make a complexion look brighter and more vibrant when chosen well.

Cool Hair Colors

Cool shades contain more blue, violet, or sometimes green-based influence.

Examples include:

These shades tend to reduce the visual appearance of warmth.

Neutral Hair Colors

Neutral colors sit between warm and cool.

Examples include:

Neutral shades can be useful when someone does not want their hair to look obviously golden or obviously ashy.

One important point: “ash” does not simply mean grey.

In professional hair coloring, ash describes a cool tonal direction used to reduce warmth.

Likewise, “gold” does not necessarily mean bright yellow. It describes warmth within the color formula.

Understanding these terms makes salon consultations significantly easier because you can describe the result you want rather than relying on vague shade names.

How to Determine Your Skin Undertone

Skin undertone is different from skin depth.

Someone can have very fair, medium, olive, brown, or deep skin and still have warm, cool, or neutral undertones.

Professional hair-color advice often divides undertones into three broad categories:

L’Oréal Professionnel’s current guide similarly uses these categories when discussing hair-color selection.

Possible Signs of a Warm Undertone

Warm undertones may show more:

Some people with warm undertones find that gold jewelry appears especially harmonious against their complexion.

Possible Signs of a Cool Undertone

Cool undertones may appear:

Silver jewelry may appear particularly flattering on some cool-toned complexions.

Possible Signs of a Neutral Undertone

Neutral skin has a more balanced combination of warm and cool characteristics.

Both silver and gold jewelry may work equally well.

You may also have heard of the vein test: blue-looking veins are commonly associated with cool undertones, green-looking veins with warm undertones, and a mix with neutral undertones. L’Oréal Professionnel includes this as one possible way to estimate undertone.

Do not treat that method as a laboratory test.

Lighting, skin depth, vein visibility, tanning, and surrounding colors can make it unreliable.

A better approach is to consider several clues together and, when possible, compare warm and cool colors around your face in natural daylight.

Should Hair Color Match or Contrast Your Skin Undertone?

This is where rigid online rules often become misleading.

You may hear:

Warm skin must wear warm hair.

Or:

Cool skin must wear cool hair.

Neither rule is universally correct.

In fact, professional color recommendations sometimes use contrast deliberately. L’Oréal Professionnel notes that stylists may recommend cooler shades to balance some warm complexions and warmer hair colors to create flattering contrast against some cool undertones.

The better question is what effect you want.

Matching Undertones

Matching can create a cohesive, soft result.

Examples:

Contrasting Undertones

Contrast can make the hair stand out and prevent the complexion from appearing overly monochromatic.

Examples:

There are no absolute rules.

Eye color, natural hair color, personal style, makeup, clothing colors, and how dramatic you want the change to look also matter.

Use undertone theory as a starting point, not a restriction.

If copper makes you feel fantastic even though an online quiz says you are “supposed” to wear ash brown, the quiz does not get the final vote.

Hair Colour Chart Wheel for Blonde Hair

Blonde hair is where color-wheel knowledge becomes especially useful because very small tonal changes can dramatically alter the final appearance.

A pale blonde may look:

depending on the pigments introduced during toning.

The underlying pigment matters.

If hair has been lifted to pale yellow, violet is typically the corrective direction for reducing yellow. Wella explains that violet sits opposite yellow and can therefore balance yellow-toned blonde.

If the hair is more yellow-orange, a formula containing both violet and blue influence may be required.

If it is strongly orange, the hair may simply not be light enough for the desired pale blonde result.

This is a critical distinction.

Toner is not bleach.

Toner adjusts the hue of sufficiently light hair. It does not take level 7 orange hair and magically turn it into level 10 platinum.

Blonde clients should therefore discuss two separate goals with their stylist:

  1. How light do I want to be?
  2. How warm or cool do I want the blonde to look?

These are not the same decision.

A person can have a beautiful level 8 warm honey blonde or a cool level 8 beige-ash blonde.

The level defines brightness.

The toner defines character.

Hair Colour Chart Wheel for Brunette Hair

Brunettes often assume color theory matters only for blondes, but that is wrong.

Brown hair contains combinations of red, orange, yellow, blue, and other pigments depending on its depth and tonal direction.

When dark brunette hair is lightened for:

red and orange undertones often become visible.

If the goal is a cool brunette, those exposed warm tones need to be controlled appropriately.

Blue can help neutralize orange, while green-based or matte directions may reduce excessive red. Wella’s professional correction guidance specifically pairs orange with blue and red with green.

Brunette color families include:

Do not assume that “brown” means neutral.

A chocolate brunette can be intentionally warm.

A mushroom brunette is typically cooler.

Mahogany may contain red or violet influence.

Ash brown contains cooler pigments designed to reduce warmth.

If your brunette repeatedly turns orange after coloring, the issue may be that warm underlying pigment is becoming exposed as the artificial cool pigment fades.

A colorist can account for this when choosing the initial formula and maintenance plan.

Hair Colour Chart Wheel for Red, Copper, and Auburn Shades

Red hair is more complex than simply “red.”

The family includes:

Copper sits closer to orange.

Strawberry blonde typically combines blonde, gold, and red/copper influence.

Auburn sits deeper and commonly blends red with brown.

Burgundy and some wine shades move toward red-violet.

When choosing a red, think about both depth and direction.

For example:

Light copper blonde
Bright, warm, orange-red influence.

Medium auburn
Deeper brown-red warmth.

Red-violet brunette
Cooler and more dramatic.

Red pigments can also fade noticeably, so maintenance becomes part of the decision. Frequent hot-water washing, heat styling, UV exposure, and unsuitable cleansing routines may contribute to faster loss of vibrancy.

The color wheel becomes useful when red is unwanted.

If someone wants a neutral brunette but their hair keeps showing too much red, green is the opposing corrective direction.

But do not attempt aggressive green correction blindly at home.

Too much green pigment on porous or overly lightened hair can leave an unwanted dull or green cast.

Corrective color is one of the situations where professional formulation can prevent a relatively small problem from becoming a larger one.

How Hair Color Numbers and Letters Work

Hair-color boxes and salon formulas often contain codes such as:

These codes usually communicate some combination of level and tone.

The problem is that numbering systems are not universal.

One manufacturer may use one number for ash, while another uses that number for a different tonal family. Therefore, do not memorize one brand’s code and assume it applies everywhere.

In general:

The first number usually indicates depth or level.

The characters or numbers after a decimal, slash, or dash describe tonal direction.

For example, depending on brand:

Wella’s own numbering system, for example, separates depth from major and minor tones, and the company advises using its specific shade chart when formulating.

This is why copying a salon formula from TikTok can go badly.

If someone’s stylist writes “7/81,” that code belongs to a specific professional color system. Buying a 7.81 from an unrelated manufacturer does not guarantee an identical color.

Always read the chart provided by the actual brand you are using.

Shade names are marketing-friendly.

Shade codes are technical—but only within their own system.

Why Your Starting Hair Color Changes the Result

Imagine three people applying the same medium copper dye.

Person A starts with pale blonde hair.

Person B starts with light brown virgin hair.

Person C starts with previously dyed black hair.

They will not get the same result.

Hair color is partly transparent. The new pigments interact with what is already inside or on the hair.

Your result depends on:

Previously colored dark hair is particularly important.

The familiar salon principle that color does not reliably lift previously deposited artificial color means putting lighter permanent dye over dark box dye often fails to create the light result people expect.

The hair may need artificial pigment removed or lightened first.

Likewise, highly porous bleached ends may grab cool toner much more strongly than healthier roots, producing uneven results.

The hair colour chart wheel helps predict tonal interaction, but it does not erase color history.

That is why professional colorists ask seemingly boring questions such as:

These questions matter more than your inspiration photo.

Hair remembers previous chemical services even when you cannot clearly see them anymore.

How to Choose a Hair Color Step by Step

Choosing the right shade becomes much easier when you stop jumping straight to the final color.

Use this sequence.

Step 1: Identify Your Current Level

Determine approximately how dark or light your starting hair is.

Do this in natural lighting when possible.

Step 2: Identify Existing Tone

Is your hair:

Step 3: Define Your Desired Level

Do you want to:

Going darker is generally much simpler than significantly lightening previously colored hair.

Step 4: Define Your Desired Tone

Choose the overall direction:

Then make it more specific:

Step 5: Use the Hair Colour Chart Wheel

If there is unwanted pigment, identify its opposite.

Step 6: Consider Your Complexion

Decide whether matching or contrasting your skin undertone creates the look you prefer.

Step 7: Consider Maintenance

An icy blonde may require much more upkeep than a dimensional brunette close to your natural color.

The best shade is not merely the prettiest result on day one.

It is a color you can realistically maintain.

Common Hair Colour Chart Wheel Mistakes

Knowing basic color theory can create false confidence.

One of the most common mistakes is assuming that complementary colors literally “erase” each other.

They neutralize visually when used in appropriate proportions.

Too much corrective pigment can create a new problem.

Other common mistakes include:

Purple shampoo is a good example.

Because violet balances yellow, it can help maintain blonde hair that develops yellow warmth.

But if your hair is dark orange after bleaching, purple shampoo is not going to turn it icy blonde.

Similarly, blue shampoo may help control orange tones in some brunette or darker-blonde situations, but it will not correct major uneven bleaching.

Color maintenance and color correction are different jobs.

If your hair has bands of black, orange, yellow, and pale blonde, that is not a “which shampoo?” problem.

It is a color-correction problem.

At-Home Hair Coloring vs Professional Color

At-home color can make sense for straightforward jobs.

Examples may include:

Major transformations are different.

Professional help becomes more valuable when you want to:

Color correction requires more than knowing that orange and blue sit opposite one another.

A colorist must consider how much blue is needed, at what level, with what base shade, using what developer, on which areas of the head, and for how long.

Hair condition also limits what is possible.

Hair that is already severely weakened by repeated lightening may not safely tolerate another aggressive bleach session simply because the desired color requires additional lift.

Whenever using oxidative hair color or lightener, follow the product’s safety instructions, including any required allergy alert or strand testing. Professional product instructions such as Wella’s technical materials specifically include allergy-alert requirements for color services.

A beautiful color is not worth destroying the hair trying to reach it in one appointment.

How to Maintain Your Chosen Hair Color

Choosing the correct shade is only half the job.

Hair color changes as pigments fade and the underlying warmth becomes more visible.

That is why a cool salon blonde may gradually appear more golden after several weeks.

A good maintenance routine can include:

Purple and blue products should be used based on the tone you actually see.

Wella’s guidance explains that violet products target yellow, while blue pigments help with orange.

Do not use heavily pigmented shampoo every day simply because your hair is colored.

Too much pigment can make some blonde hair look dull, muddy, overly violet, or unusually cool. Wella’s current guidance describes purple shampoo more as a treatment wash used when unwanted warmth appears than something every blonde automatically needs daily.

Maintenance should preserve your intended tone—not constantly fight an imaginary problem.

If your beige blonde looks exactly how you want it, there is no reason to keep adding violet until it turns silver.

Final Thoughts on Using a Hair Colour Chart Wheel

The hair colour chart wheel is one of the most useful tools for understanding why hair color behaves the way it does.

Its most important principle is easy to remember:

Professional hair-color education consistently uses these complementary relationships when explaining toning and color correction.

But the wheel is not the entire formula.

Before choosing a shade, you also need to know:

  1. Your current hair level
  2. Your underlying pigment
  3. Your previous color history
  4. Your desired level
  5. Your desired warm, neutral, or cool tone
  6. Your hair’s condition
  7. Your realistic maintenance commitment

Skin undertone can help narrow your options, but it should guide rather than dictate your decision. Matching warm with warm or cool with cool can create harmony, while deliberately contrasting undertones can create an equally flattering result.

The biggest misconception is believing that the right toner can solve every color problem.

It cannot.

If hair has not been lifted to the required level, toning cannot replace lightening. If hair is damaged or unevenly colored, professional correction may be necessary.

Use the wheel as a map.

You still need to know where you are starting before deciding which direction to travel.

Frequently Asked Questions

How do I use a hair colour chart wheel?

A hair colour chart wheel is mainly used to understand relationships between hair-color tones and identify the complementary pigment needed to neutralize an unwanted color.

Start by identifying the unwanted tone in your hair.

If the hair looks yellow, find yellow on the wheel. Its opposite is violet, meaning violet pigment can help neutralize excessive yellow.

If the hair looks orange, the opposite is blue.

If the hair looks red, the opposite is green.

Professional Wella color guidance uses the same complementary system and explains that colors opposite one another can neutralize unwanted tones.

However, you should also determine your hair level before choosing a toner.

For example, strongly orange level 6 or 7 hair may not be light enough to become platinum blonde. Applying violet toner cannot overcome insufficient lightness.

Think of the color wheel as a tone correction tool, not a complete coloring formula.

You also need to consider previous dye, porosity, hair condition, desired depth, and the manufacturer’s specific color chart.

For simple maintenance, this knowledge can help you choose between purple and blue toning products.

For major corrective work involving uneven bleach, bands, dark artificial color, or severe brassiness, a professional colorist can formulate much more accurately.

What color cancels orange hair?

Blue neutralizes orange.

Blue and orange sit opposite one another on the traditional color wheel, which means blue pigment can reduce the appearance of orange warmth.

Wella’s professional guidance specifically recommends blue tonal directions when correcting orange hair.

This is why blue shampoos and blue-based toners are commonly associated with brassy brunettes and darker blonde hair.

However, not all “brassiness” is orange.

If the unwanted color is pale yellow, violet is more appropriate.

If the hair is red-orange, a formula may require a more complex balance.

The level also matters.

Suppose you want a very pale ash blonde but your hair is currently dark orange. Blue can make that orange appear more neutral, but it cannot make the hair several levels lighter.

Further controlled lightening may be necessary before the desired blonde is achievable.

Do not repeatedly apply strong blue pigment without evaluating the result. Excess corrective color can produce an overly dull or cool finish.

Color correction requires balance.

Identify the exact warmth first, then choose the complementary direction.

What color cancels yellow or brassy blonde hair?

Violet or purple neutralizes yellow.

Yellow and violet sit opposite each other on the color wheel. Wella’s professional education materials explain that violet pigment can therefore be used to reduce unwanted yellow tones in blonde hair.

This is the principle behind purple shampoo.

Purple products can be particularly useful for:

But purple shampoo does not solve every type of brassiness.

If your hair is noticeably orange, blue is the more relevant complementary color.

If it is red, the corrective direction moves toward green.

This explains why someone can use purple shampoo repeatedly on orange hair and see very little improvement.

The product is addressing the wrong color.

Also remember that toning changes hue rather than significantly changing level.

If hair remains too dark for your intended blonde, more toning will not make it platinum.

The hair must first reach an appropriate lightness before a pale toner can create the desired final shade.

What hair color is best for warm, cool, or neutral skin undertones?

There is no mandatory shade for any skin undertone.

Warm complexions can work beautifully with colors such as caramel, honey, chestnut, warm brown, copper, and golden blonde, but cooler colors can also create attractive contrast.

Cool undertones may pair naturally with ash brown, cool brunette, platinum, or icy blonde, while warmer shades such as copper and strawberry blonde can intentionally provide contrast.

People with neutral undertones often have particularly broad flexibility.

L’Oréal Professionnel’s current hair-color guidance similarly emphasizes that there are no absolute rules and includes examples where stylists may use contrasting hair temperature to balance a complexion.

Instead of following a rigid warm-equals-warm formula, consider:

A dramatic icy blonde may look excellent but require far more maintenance than a brunette close to your natural shade.

Likewise, a bright copper may suit your complexion beautifully but need frequent color refreshing.

The “best” color is therefore a combination of appearance, hair condition, lifestyle, and what you genuinely enjoy wearing.

Why does my hair turn orange when I try to go blonde?

Hair often turns orange during lightening because warm underlying pigment becomes exposed before the hair reaches a pale-blonde level.

Natural dark hair contains underlying red, orange, and yellow pigments. As color is lifted, these become visible in stages.

Professional lightening charts show this progression from deeper red or red-orange pigments through orange, yellow-orange, yellow, and eventually pale yellow as hair becomes lighter.

If the lightening process stops while orange pigment is still dominant, the result will look orange or brassy rather than blonde.

This does not necessarily mean the bleach “failed.” It may mean the hair has reached an intermediate stage.

Blue pigment can neutralize orange if the goal is a color at that depth.

But if your goal is very light blonde, simply adding blue toner may create a cooler level 7 or 8 result rather than the pale level 9 or 10 blonde you expected.

Further lightening may be necessary—but only if the hair is healthy enough to tolerate it.

Repeatedly bleaching compromised hair can cause serious breakage.

For major dark-to-blonde transformations, a professional colorist can assess whether the desired level should be achieved in one appointment or gradually over several sessions.
